[DML] Re: Idle Speed ECU



The thermistor is a variable resistor, not a switch. More resistance = higher speed. If you short it out, it goes lower. Since it's warm it's already as low as it will go. Try opening up the connection and see what happens. 

Sorry - I don't know the resistance values offhand. Could get it Tuesday.

I works fine for normal operation however, cold idle speed increases during the winter didn't seem happen - at any low temperature - like 20F, etc. So now that things are warmer I wanted to check it - plus - with the right relay set-up I thought I could fabricate an increased idle speed when I turn on the AC.

Problem is, I can't get the ECU to increase the idle speed by simply crossing the two wires from the thermistor - which I believe is all that is required. Thus, why I believe that circuit is defective.
